- a rearwardly extending flange 9 integral with and extending at rightangles to the upper end of the front part 1, a forwardly extendingflange I0 integral with and disposed at right angles to the i upper endof the rear part 8, and a depending 1 ared trough-like 4part Il whichmerges at the upper ends of its front and rear into the rear and forwardends of the Yflanges 9, I0 respec` tively. The part II coacts with theparts 6, Al, *8, flanges l?, l0 and sidecheeks 4, 5 to form -a H closedcompartment l2ffor the reception of Water toebe heated.- The part Il inconnection with the cheeks 4, 5 form an open top compartment I3'for theglue or other coating. The compartment I3 is of lessv height andoflesslength than the compartmentlZ. The portion 3 has integral vtherewith, at suit-able points lugs I4 formed with -threaded openingsfor engagement by holdfast means, not shown for the purpose of anchoringsaid body portion to,A between and in suspended relation with respecttothe side cheeks. The f `holdfast means are to extend` through the side4cheeks and' engage in thev threaded openings of the lugsll.

A water inletV I5 is. provided forthe compart- -lment l2, VThe latterhas'arranged therein an electric heater I6 for the purpose of heatingYthe-water within suchlcompartment and .said .heater .has.associatedvtherewith `a .controlling element I8 and drain I8b aresuitably secured with one of the side cheeks.

The side cheeks 4, have their upper terminal` portions of greaterthickness than the remaining portions thereof and suchupper'terminalporf tions are indicated at 251'andareiof like form. Each portion 2l) isformed with a squared cut# out 2i entirely therethrough and which opensj into the compartment I3, a rectangular cut-out 22 forwardly of thecut-out 2I and having a portion thereof indicated at 23 l(Figure 5)opening .into the compartment I3, a rectangular cut-out ..24 forwardlyof and of greaterlength than the cut-out 22 Vand which opensronly at theouter side and the top of the portion 2U, and a squared cut-out 25forwardly of the cut-out 24 which kdoes not open into the compartmentI3, but

opens at the outer side and front end of the portion 26. The cut-outs2I, 22 and 25 also open at the top of the portion 26. The cutout 22 isprovided at eachl end of its bottom with a groove 25. The cut-out 2| isspaced from the cut-out 22 by a part 21 of the portion 26 and whichconstitutes a partition. The cutout 24 is spaced from the cut-out 22 bya part 28 and which constitutes a partition, andthe cutout 25 is spacedfrom the cut-out 24 by a part 29 of the portion 28 and which constitutesa partition. Secured to the inner face of the part 21 is a block 3 for apurpose to be referred to. The front of the base structure I, which isprovided bythe part 1 of the body portion 3 has secured to its outerface a pair of spaced upstanding brackets 3l which are arranged inalignment, are of like form and each provided at its upper end with anannular bearing 32. The purpose of the bearings 32 will be referred to.

The machine includes a coating or glue applying roll 33, a wiping rollor doctor 34 for the roll 33 which is arranged forwardly of and inproximity to the roll 33, a lower coated material guide roll 35 arrangedabove the roll 34 and in proximityto the roll 33, and an upper coatedmaterial guide roll 36 arranged over and in proximity to the roll 33.The rolls 33, 34 are supported from the base structure I. The rolls 35,36 aresupported from the super-structure 2. Mounted. in the cut-outs 2Iof the portions 28 of the side cheeks 4, 5 are bearing blocks 31,

for the shaft 38 .of the roll 33. The inner ends y of the blocks 31 havesecured thereto squared A plates 39 extending laterally from the blocksyand k,opposing the inner faces of the portions 20 to prevent the blocksshifting outwardly from the side cheeks. l The blocks 31Uextend abovethe .l uppervsurfaces of the side cheeks, vThe roll 33 l carriedbytheshaft 38 lis of materially greater Adiameter than the rolls 34, 3 5, 36.The diameter of the roll 33 is such as to extendmaterially formed withopenings 4I between their vertical medians and their rear ends. Theshaft for the wiping roller 54 is indicated at 42 and it is journaied inthe openings 4I of the blocks 40. The inner end of the blocks 4U areformed with rectanguiar plates 43 of greater height and length than theblocks 46. The plates 43 are positioned against the inner faces of theportions 20 of tne side cneeks and arrest the outward shifting or' theblocks 4u relative to the cut-outs 22. The

`blocks 3b are arranged between rollers 33, 34

t and the saidA side portions 20 and act to scrape cut-.out 25.

,'tne. glue from the ends of the said rollers.

The parts 28, 29 of the portions 20 of the side 'a'structure for theshifting of the blocks lengthwise of the side cheeks, in oppositedirections for the purpose of moving the roll 34 to and from the roll33, or for adjusting the roll 34 relative tothe roll 33. The saidstructures are of like form` and generally indicated at 46 and eachconsists .of a rod 41 which is mounted in the cut-outs 22, 24,/25 andextends through the openings 44, 45. Each block 40 has a right handthreaded socket 48 in its forward face (Figure' 5) and engaging with thewall of such socket is a threaded inner end 49 of the rod 41. A lock nut56 is carried by the rod 41 and abuts the forward surface of the block48. The rod 41 in proximity`to the part 28 of a portion 20 carries acollar 5I secured stationary on the rod 41 by a set screw 52.Surrounding the rod 41 and interposed between the collar 4I and the part2S of a portion 26 is a coiled controlling spring 53 for the rod 41.That end of the rod arranged in the cut-out 25 is threaded left-hand, asat 54 and engagingtherewth is a coupling head 55 formed with anoval-shaped opening or slot 56. The coupling 55 extends forwardly fromthe A lock nut 51 is mounted on the part 54 of the rod 41. The purposeof the right hand and left hand threads on opposite ends is vto alignthe wiping roll with the glue roll on from a coupler and has fixedthereon a .collar 6|] provided with a crank handle 6I carrying at itsouter end a latching structure 62 including a spring controlled latchingpin 63. Fixed to one of the side 'cheeks and correlated with thelatching pin 63 is an upstanding substantially semi-circular plate 64having .a depending extension 65. The outer face'of the plate 64 isformed with a circular row of spaced designated sockets 56 whichareadapted to selectively receive the pin 63 and latch the shaft 59 inits adjusted position. The indicia which associates with the sockets 66vis designated at 61, and it is for the purpose of determining the degreeof adjustment `'ofthe' roller 34 with respect to the roller 33.

' After'the desired adjustment has been had by the swinging of thehandle 6I in the desired vIlhej roll 34fat`e'a'chiend, only one endshown (Figurev 5,) is provided with a reduced portion 68 which ismounted in a .cavity 69 formed in the plates 43.

The super-structure 2 includes a'pair of spaced `parallel side cheeks(19 of like form and of less `length than the length of the lbasestructure.

Each side cheek 18 `includes a rear part 1i and aforward part 12, thelatter is of less height than the p-art 1l. The bottom of the part 12 isvarranged above the bottom of the part 1I. The forward end of the part1I forms a shoulder 13.

Arranged against the shoulder 13 and extendingl forwardly from the part'l2 are supporting bars 14for a platform or table 15. The parts 1l, 12,

bars 1li and platform 15 are suitably secured to- The platform 15extends forwardly belyond the front of the base structure l and may beformed with a depending handle or grip. The

gether.

platform 15 extends inwardly to an extent to be `arranged over the roll34 and under the roll 35 and has a beveled inner end edge 16 (Figure 3).The inner corners of the platform 15 are cut-out as at 15b to provideclearances and to reduce the width of the inner end terminal portion 15vof the-platform. The side cheeks 16 are formed `without-outs 11 (Figurel) for the upper end bar 8D for a series of forwardly extending spaced-rgravity lowering weighted pick-up fingers 8|,

4which seat at their forward ends on the top of the applying roll 33.

The bar 86 is formed with reduced end terminals which are removablymounted in the notched extensions 82 at the upper end of the rear of thecheeks 16. The plates 19 are also formed with notches 83 for removablyreceiving the bar 83. The extensions 62 are arranged above the notches83.- The pick-up structurel can be bodily adjusted relative tothe roll33to dispose the pick-up fingers at diierent'levels with respect to theroll 33. The extensions 82 and notches-83 provide for this adjustment,as

`whenbar 38 is mounted in the extensions 82 the pick-up fingers will bedisposed at a higher level `than when the bar 88 is mounted in thenotches 83. The adjustment of the pick-up structure will provide forchanging the distance between the roll 33 and the pick-up fingers.

VThe shaft of the guide roll is indicated at 84 and it is eccentricallymounted in head 85 formed on the inner ends of bearings 86 positionedvinopenings -81 (Figure 4) formed in the side cheeks 19. Secured to theheads by threaded shanks 88 are blocks 89 fixed to forwardly extendingspring controlled adjusting rods 90 which are slidably mounted inapertured arms 9! formed on the inner faces of the parts 12 of thecheeks 13. The rods 9!! are threaded,

as at 92 and threadably engaging with the rodsy,

98' are adjusting nuts 93 therefor. The nuts 93 are arranged forwardlyof the arms 9i. The arrangement of the rods 98 is such that if the rods98 are adjusted'inwardly the roll 35 will be swung away from the roll33, but if the rods.99 are adjusted outwardly the roll 35 will -be swungtowards the roll 33.

Theguideroll 3.5 is of less length thanthe `guide roll 35 and a pair ofoppostely disposed peripherally .threaded adjustable.shafts;or sup- 755ports 94 havingpointed or ta-pered .inner ends 94al to rotatably suspendthe roll 36 above the roll 33 and also above the roll 35, :butrearwardly of the latter. The shafts 94 threadedly engage with" tubularmembers 94h and with spacers 94c arranged at the inner endsof themembers94l?. The members Stili` are slidably arranged in ovalshapedaligned slots. 91, formed in the superstructure 2 near theupper edges ofthe sides of the latter. The shafts 94 extend inwardly from thespa'cers94c and have their ends 94a engage in tapered sockets 94d formedin the ends of the roll 36. The spacers Mclare arranged against theinner Vfaces of the sides of the superstructure 2. .y

The blocks 89 are'formed with headed pivots 95 and extending rearwardly.from the said pivots to the shafts-94 are links 96 formed with openings96a (Figure .2) in vproximity to their rear ends for the passage of saidshafts 94.

The mannerof connecting the rolls 35 and 36 together as aforesaidprovides that when the nuts 93 are turned clockwise the roll 35 is movedup from thetable and awayfrom the roll 33 due to the fact that thebearingsfor the roll 35 are placed eccentrically as shownby Figure 1.Also when the nut is turned as explained, not only does the roll 35 moveaway from the roll 33 but the roll 36 is also moved away from the roll33 due to the fact that the pivots 95 connect the eccentric bearing 86with the'links 96 andthe roll '33, which thereby moves in conjunctionwith the roll 35.

The purpose of this linkage is to adjust both rolls 35, 36simultaneously. For example; if it is desired to glue a thin sheet ofpaperthe roll 35 will be close to the table and close to the glueV roll,'and roll 35 will be close to the glue roll. I-Iowever, when it is'desired to glue heavier material, for example: a light cardboard,morecdistance is required :both between the table and roll 35 and theglue roll and roll `33. Therefore, if Ythecardboard to be glued is, forexample, als of an inch thicker than the paper previously glued, the`nuts 93 are adjusted so that roll 35 is the properdistance from thetable, andby adjusting it for this distan-ce it is also adjusted awayfrom the glue roll due to the eccentricity. Alsoby adjusting -the roller35 to the proper height from theY table the roll `36 is pulled by thelinks 96 to the right as shown in Figure l, the center being supportedin the slots 91 and therefore moves in a straight line, and by moving ina straight line theV distance between the roll 36 and the roll 33 isalso increased to accommodate the heavier material.

The end walls of the slots 91 correlate with the members 94b to limitthe extent o-f the bodily shifting in unison of the rolls 35, 36 inopposite directions.

As is well known, the glue or coating applying roll and the wiping rollforming elements of machines of the class to which the machine formingthe Vsubject of this application belongs, are drivenfrom a suitablepower transmission operated by a prime mover, such as an electric motor,and although it is not shown that the shafts `of rolls 33, A3l! areconnected with a driving means for such shafts, it is to be understoodthat such Y shafts are to be suitably connected toV any suit-.abledriving means therefor, such vby -Wayy of example'asshown by thepatent aforesaid.

Each spring controlled rod 93 coacts with its correlated nut 93, arm 9iand block 89 to form a spring -controlled combined adjusting andV,latchiiig structure for a head,85.

The work to be coated is mounted on the table 'l5 and is fed from theinner end of the latter to between the roll 33 and roll 35, from therethe coated work is conducted to between rolls 36, 33, and after itpasses roll 3B, it is picked up and .conducted upwardly and off of themachine by the fingers 8|. The fingers 8| have their forward endsinclining rearwardly from bottom to top against which travels the coatedwork. The rollers 3A, 35 not only function as guides but also as coatedwork retainers as they hold the coated work against the roll 33.

Although the machine is specifically referred to as a machine forapplying glue to one face vof an object, yet it is to be understood thatitis also adapted for applying coatings of materials other than glue.The sliding bearings for the wiping roll and the horizontal shiftableadjusting means for said bearings, when taken together may be termed apair of adjustable horizontally shiftable parallel carriers foradjusting the wiping roll.
